Preheat oven to 275°F. Set a wire rack inside a baking sheet. Preheat a waffle iron to level 5 or medium-high to high.
For the chicken, make a breading starting by lining up 3 shallow dishes. In the first, season the flour with salt and pepper. In the second, mix the buttermilk and hot sauce; season. In the last, mix the corn flakes, granulated garlic and onion, paprika, salt, and white and black pepper. In a large skillet, heat 1/8 inch of oil over medium-high. Working in batches, dredge the chicken in the flour, dip in the buttermilk, then coat in the cornflakes, pressing so the crumbs adhere. Fry until golden, 3 to 4 minutes per side. Transfer to the rack; keep warm in the oven.
